The German company RW Energy GmbH develops tracking system with a
very low overall height, which has attracted
a great deal of interest from the
Spanish PV market. The construction,
called the s:wheel, has the advantage
of being much less susceptible to wind
damage than most other tracking systems.
A base frame, anchored to the
ground, supports a rotating assembly
with a nearly 25 m diameter, upon
which modules are installed in several
rows parallel to each other. By default, a
single-axis tracker optimized according
to the specific location, is driven electronically
by a 750 W motor; elevation
tracking is available optionally.
RW Energy belongs to the Rädlinger
Group, which has various firms active in
the construction sector - actually some
of RW Energy´s employees worked in the
development of production systems for
the automobile industry in the past.
When fully covered,
the s:wheel can contain
234 m2 of module surface
area; depending
on module efficiency,
that could amount to
up to 36 kW per unit.
